Calbuco, a stratovolcano in southern Chile, began erupting yesterday at 7pm local time. First spewing massive ash clouds then, at 10pm, erupting explosively as its fragile structure collapsed inwards. Here’s all the stunning imagery and video; we’ll keep it updated as this develops. You can see it from space! »4/23/15 2:41pm 4/23/15 2:41pm

The Calbuco volcano in southern Chile is erupting for the first time in 42 years, spewing huge amounts of ash into the atmosphere and prompting evacuations across a 24-mile wide area. And the results are absolutely stunning. »4/23/15 12:00am 4/23/15 12:00am

The increasingly active Turrialba volcano in Turrialba, Costa Rica erupted three times Thursday (including the one pictured here), followed by a smaller burst on Friday. Costa Rica's main airport in San Jose was briefly closed, and schools near the volcano suspended classes. »3/14/15 4:30pm 3/14/15 4:30pm

Papyrus rolls buried in the eruption of Mount Vesuvius in 79 AD were discovered 260 years ago in the ruins of Herculaneum. But they're so fragile that it's never been possible to read them without inadvertently destroying them — until now. »1/20/15 2:20pm 1/20/15 2:20pm

Once lava from an erupted volcano starts moving, it tends to keep moving that way, regardless of what we want. But Hawaiian researchers have figured out some ways to redirect a lava stream away from you or your property — even if the eruption goes on for several months. »12/30/14 10:20am 12/30/14 10:20am

Definitely don't try this at home (or if you happen across a volcanic vent), but if you've ever wondered what would happen if you pressed down on hot lava, this video is a must-watch. It's a great lesson in how the reality of lava differs from the way many people think of the substance. »12/18/14 1:35pm 12/18/14 1:35pm

Bárðarbunga is a subglacial volcano in Iceland responsible for a whole lot of seismic activity this week. If it erupts, it could melt the Vatnajökull glacier and produce impressive downstream flooding. At least the latest Icelandic volcano to catch our eye is a lot easier to pronounce than the last one! »8/20/14 12:34pm 8/20/14 12:34pm

What happens when you boil a can of Coke with a lava flow? Or leave tall can of an energy drink to be engulfed in molten rock? Now that your drink is steaming hot, what does it look like to try cooking ravioli with an encroaching flow? »5/26/14 11:41am 5/26/14 11:41am

An animation of a tiny volcano trying to impress its larger peers with an eruption seems like a flight of fancy, but it's really a hidden lesson in volcano morphology. The difference parallels the distinction between tiny-yet-enthusiastic cinder cones and intimidating stratovolcanoes . »5/17/14 5:31pm 5/17/14 5:31pm
